EDWIN LE ROY ANTONY, OF CAMERON, TEXAS.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 596,235, dated December28, 1897.

n Application filed June 28, 1897. Serial No. 642,601. (No model.)

tion, such as will enable others skilled in thev art to which itappertains to make and use the same, reference being had to theaccompanying drawings, making a part of this specification, and to theletters of reference marked thereon, and in which similar letters ofreference indicate corresponding parts.

My invention relates to improvements in monkey-wrenches; and its objectis to provide an improved construction of the same whereby theclamping-jaws may be quickly and readily adjusted to the nut or tapwhich is to be engaged thereby.

The invention consists in the novel construction and combination ofparts hereinafter described and claimed. y

In the accompanying drawings, Figure l is a side elevation of a Wrenchconstructed in accordance with my invention. Fig. 2 is a side elevationof the handle or frame. Fig. 3 is a similar view of the movable jaw andits shank. Fig. 4 is a vertical section on the line e' e, Fig. 1. Fig. 5is a similar section on the line a: oc. Fig. 6 is a detail View of theratchet-catch. Fig. 7 is a detail view of the sleeve-blank before beingbent into form'. Fig. S is an end view of the sleeve. Fig. 9 is a detailview of the handle or frame, looking from the under side and showing theholes in which the pins of the catch work.

In the said drawings the reference-letter F designates a frameor handlemade of metal and comprising the arms n n, connected together at oneend, and one of said arms at the opposite end being formed with astationary jaw lo. Said arm is also formed with an enlargement g'/ atthe oppositeend. There is a space between said arms to receive a movableshank T, cutaway at the inner end, forming a reduced portion T', havingupon one edge a number of rack-teeth `y2 and at the outer end formedwith a head H and a jaw la', movable with the shank. The object of theenlargement y is to form a contracted space to receive the reduced end Tof the shank T.

The letter .I designates a sleeve consisting of a metal plate bent overnear the center, forming two parallel portions a a, which embrace thearms n n. This sleeve is formed with holes h, through which and alsothrough holes h in one of the arms n pass bolts or rivets fr, by whichthe sleeve is firmly secured to the handle or frame. At one end saidsleeve is formed with lugs o, with which engage lugs e on a catch orrack-plate C, formed with teeth t, adapted to engage with the teeth onthe shank T. This plate is located in a recess b in one of the arms nand is provided with pins p, passing through holes m in the arm. Ooiledsprings S are interposed between said catch and the arm to throw theformer into engagement with the teeth of the shank. The purpose of thelugs e and ois to prevent the rack-plateO from being forced out of itsseat by the coiled springs S should the shank T be entirely withdrawnfrom the handle, the lugs e in such case engaging with or abuttingagainst the lugs o.

In use the coiled springs will force the catch or rack-plate intoengagement with the teeth of the shank of the movable jaw, thus holdingthe latter in place. To adjust the-movable jaw,the said catch orrack-plate is pushed away from the shank, so as to disengage its teeththerefrom,when the shank can be moved out in a rapid manner. The catchis then released, when the coiled springs will again force the catch orrack-plate into engagement with the shank and, sliding easily over eachother inwardly, the adjustment is quickly made to a nut or bolt bypressing the head II and the handle toward each` other, holding over thenut or bolt, thus clasping it between jaws lo lo by the engagement ofthe teeth of the catch or rack-plate with the shank-teeth automatically.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. In a wrench, the combination with the frame or handle comprising theconnected arms, one of which is formed with a jaw, a recess and anenlarged portion, and the sleeve IOC embracing said arms and secured toone of the same and `formed with lugs at the inner end, of the movableshank having a jaw at the outer end and the other end reduced and formedwith rack-teeth, the movable catch or rack-plate provided with lugsadapted to engage With the lugs of the sleeve, and the coiled springs,substantially as described.

2. In a Wrench, the combination with the frame or handle comprising theconnected arms, one of which is formed with a jaw, a recess and anenlarged portion, and the sleeve lugs at the inner end, of the movableshank 15 having a jaw at one end and reduced at the other end and formedwith racloteeth, the movable rack-plate or catch provided with lugs, theguide-pins and the coiled springs, substantially as described.
